HNLW-3000Q intelligent gas turbine flowmeter

First, the working principle
When the fluid flows into the meter, at the intake port specific integrated rectifier rectifying effect and give up, due to a flow of fluid turbine blade is angled rotational torque generated by the turbine at this time, after overcoming the friction torque and fluid resistance torque, the turbine starts to rotate. In a certain flow range, the angular velocity of the fluid is proportional to the volumetric flow rate of rotation of the turbine. According to the electromagnetic induction principle, the use of a magnetic sensor senses the fluid volume flow signal proportional to the pulse signal from the coaxial rotating wheel, the signal amplification, filtering, shaping and temperature, pressure sensor signal went into intelligent flow totalizer instrument for micro processing unit performs computational processing, and the total gas volume flow and directly displayed on the LCD screen,
The flow meter verification procedures and implementation of national JG198-94 Q / 12KF3989-2001 LWY Series turbine flowmeter corporate standards.
